Thanks Jeff
now i know that the problem with these screw-extruder presses it is
that they have extreme wear....! When used for compacting wood chips.
Industrial machines needs welding of the screw after 24 hours
of operation !!! (welding with special tungsten rods)
So "homemade" screws made be worse.
my friend from Bosnia now bought a 2nd hand  GROSS Hydraulic press
for about 8000 Euro. (new over 20.000 Euro ?)
A screw press from Malaysia would have cost about 4200Euro plus shipment
 to Europe and tax, also about 6000 Euro all together.
Best
Chris
